Below is an image of three genes located on a chromosome. Each has its corresponding promoter indicated as “P” next to the gene that gets transcribed. For each of the three genes, indicate whether the top strand or lower strand in the image serves as the template during gene expression. The diagram depicts a linear double-stranded DNA sequence containing three genes, labeled “Gene 1,” “Gene 2,” and “Gene 3.” Each gene is represented as a rectangular box with the “P” in a smaller box attached to the gene. The top strand of DNA runs from 5’ to 3’, and the bottom strand is complimentary to it running from 3’ to 5’ when the image is viewed from left to right. When reading the image from left to right, you first encounter a P followed by Gene 1. Then, you encounter Gene 2 followed by P. Finally, you encounter Gene 3 followed by P.
